Persona injury case setteled out of court. Ins co. had the documents since 4-25-14 and still no check. Is there a time limit in NJ?

Its really not been that long of a time, although it must seem like it !  Many attorneys deal with dozens of cases at one time, and have many, many documents to handle.  Your releases were probably sent to the insurance company, who will take their time in paying your claim, and then it will come to the attorney.  If you are concerned, call the attorney, ask to speak to the paralegal and ask if there is an anticipated date on which you will receive payment.
